vshummy"Very low leukocyte alkaline phosphatase (LAP) as a result of low activity in malignant neutrophils vs benign neutrophilia (leukemoid reaction) in which LAP is increased due to increased leukocyte count with neutrophilia in response to stressors (eg, infections, medications, severe hemorrhage)."+32019-06-01T18:28:40Z
lispectedwumbologistBecause you'll see some blast cells in a leukemoid reaction. It won't be 0%. +12019-05-31T23:49:04Z
paulkarrAlso, don't get confused with 0% Basophils. Basophils are seen in CML but not in Leukemoid reactions. I just went with LAP because they pointed it out in the lab values. Had that not been there, I would have chosen "0% basophils"+2019-12-04T04:06:11Z
nor16yeah but pathoma doesnt help here...+12019-07-29T16:51:40Z
thotcandyYeah but LAP is normally 20-100 so a 100-250 U/L is still + which would indicate Leukemoid reaction, no? That's why I didn't pick it, Because I figured 250 u/l was just some random number and it didn't make sense.
a -LAP would be in the normal range, 20-100 which would THEN indicate CML. +2020-02-06T04:31:48Z
thotcandyLAP 100-249 do not fall into the answer choice but would still be considered high value and thus +LAP to indicate leukemoid. A LAP- would be in the normal values which is 20-100, not below 250 like the answer choice indicates. +2020-02-06T04:33:39Z
